There seem to be several bravo pumps on the market that look like they'll do the tubes and airfloor on my aerotec 420. There's a btp model and a bst model and a bst turbo? Can anyone tell me which is suitable. If they all are then I will go for the cheapest

Really enjoying the 420, its going well and planes the 3 of us easily with a 2st 15hp mariner. Not enjoying inflating it by hand though!

You don't have to go down the Bravo route, especially if you (like me) keep the SIB inflated/transported all season. Still using the same set up below and it's still working great and will get HP floors to 12 psi:

I have to admit with the Aerotec 380 I'm tending to stick to the Bravo 9 type OE footpump that comes with them new and the Bravo elec pump is being left in the car.

Fair enough there is a fair bit of volume to fill to get the tubes to shape but after that the Bravo 9 (compared with the Zodiac supplied HP footpumps of 10yrs ago) seems to get the tubes to pressure without breaking a sweat.

The HP floor on the Aerotec with its two smallish panels separately inflated also seems really easy with the Bravo 9 footpump... far easier than a large flat air floor with HP keel all on one valve with something like a 360 Fastroller.

Part of it is noise... many of the places we launch these days are quiet enough for the Bravo elec to be intrusive when it kicks into HP machine gun mode... not a problem at a roadside car park though.
